[embodiment]
As depicted in figs. 1 and 2, the utility model electric connector 100 comprises insulating body 1, is contained in the first terminal 2 (negative terminal), second terminal 3 (positive terminal) of insulating body 1 and covers the shielding casing 4 of insulating body 1.
As shown in Figure 3 and Figure 4, insulating body 1 roughly is cuboid, the upper surface 12 that it has front end face 11, the rear end face 13 relative with front end face 11 and connects front end face 11 and rear end face 13.Front end face 11 is concaved with first receiving space 14 backward along the butt joint direction, and the butt joint direction also is defined as first direction.Stretch out a columned excrescence 15 to front end face 11 1 pleurapophysis in first receiving space 14, this excrescence 15 portion within it is formed with second receiving space 16, and this second receiving space 16 runs through rear end face 13 backward.For convenience of description, the direction vertical with upper surface 12 is defined as vertical direction.Described insulating body 1 further is provided with the accepting groove 17 that communicates with first receiving space 14, and this accepting groove 17 runs through rear end face 13 to be used for accommodating the first terminal 2.Upper surface 12 is extending upward projection 120 near front end face 11 places.
The first terminal 2 comprises along first direction and extends and be flat main part 21, autonomous body 21 1 lateral bucklings and the elastic arm 22 that extends towards first direction and connect the kink 23 of main part 21 and elastic arm 22.Elastic arm 22 is provided with recess 24 at middle section, and main part 21 is provided with the breach 27 relative with recess 24.Uvula portion 25 grows from breach 27 inboards and towards the recess that oppositely protrudes into elastic arm 22 24 of first direction.This uvula portion 25 comprises the arc-shaped head 252 of the flat part 251 that links to each other with main part 21, close front end face 11 and the abutting part 253 between flat part 251 and head 252.The free terminal of arc-shaped head 252 bends downwards and towards first direction.The purpose that uvula portion 25 is set is to guarantee that butt connector (not shown) at first contacts with the first terminal 2 when butt joint, simultaneously butt connector is played guide function.Therefore, head 252 is compared kink 23 more close front end faces 11, also is that kink 23 is positioned at head 252 rears on first direction.Abutting part 253 in the vertical directions exceed elastic arm 22.Like this, butt connector may at first contact with head 252 during insertion.Because head 252 is set to arc shape, thereby can prevent that butt connector from withstanding uvula portion 25 and causing the damage of inserting difficulty even little tongue.Described elastic arm 22 is at the contact site 26 that is extended with bending away from front end face 11 1 sides, and this contact site 26 can strengthen the contact engaging and separating force of butt connector.In the vertical direction, contact site 26 exceeds abutting part 253, and on the butt joint direction, abutting part 253 is compared contact site 26 more close front end faces 11.Second terminal 3 roughly is tuning fork-like, and it comprises horizontally extending base portion 31 and first haptic element 32 that is oppositely arranged and second haptic element 33 that extend forward from base portion 31.Also be provided with some little projections 34 in the both sides of base portion 31, to allow second terminal 3 better be immobilizated in second receiving space 16.
As Fig. 2 and shown in Figure 5, in electric connector 100 assembling process, the first terminal 2 inserts host cavity 17 from the rear end face 13 of the body 1 that insulate, and the abutting part 253 and the contact site 26 of the first terminal 2 protrude in first receiving space 14.Second terminal 3 is in rear end face 13 is contained in second receiving space 16.Shielding casing 4 be coated on from back to front insulating body 1 around, opening 410 correspondences of shielding casing 4 are fastened in the projection 120 on the insulating body 1, simultaneously, the recess 18 of corresponding setting is interlocked on the shell fragment 421 on the shielding casing 4 and the insulating body 1.
